title: Stereoselective synthesis of alpha-glycosyl phosphites and phosphoramidites via O-selective glycosylation of H-phosphonate derivatives.
abstract: A highly stereo- and chemoselective glycosylation of H-phosphonate derivatives with glycosyl iodides was discovered as a reverse reaction of the formation of a glycosyl iodide from a glycosyl phosphite and I- under mild acidic conditions. Further study on the unique reaction showed that the reaction provided various alpha-glycosyl phosphites and phosphoramidites in a highly stereoselective manner with complete O-selectivity.
